Two vectors have magnitudes of 10 and 15. The angle between them when they are drawn with their tails at the same point is 65. The component of the longer vector along the line of the shorter is 6.33 .
A vector is a quantity or phenomenon that has two independent properties: magnitude and direction. The term also denotes the mathematical or geometrical representation of such a quantity. Examples of vectors in nature are velocity, momentum, force, electromagnetic fields, and weight.
The taller component will be 15 . There will be two components taller component , one in the direction of shorter component and other perpendicular to the shorter wavelength .
The component of longer wavelength in the direction of shorter will be
= 15 cos (theta ) = 15 cos (65) = 6.33
where theta is the angle between both the vectors

Yes.
-- 'Acceleration' does NOT mean 'speeding up'.
It means ANY change in the speed OR direction of motion ...
speeding up, slowing down, or turning.
-- If an object is NOT moving in straight line at constant speed,
then its motion is accelerated.
-- In circular motion, or even just going around a curve,
the object is accelerating, because its direction is constantly
changing, even if its speed is constant.

It's on your exam boards specification or just google it. the foundation paper will have the same equations as higher, but higher just has more.
Answer:
using Snells law
Oi = angle of incidence = 58.0°
ni = index of refraction of air = 1.0003
nr = index of refraction of glass = 1.47
c = speed of light in vacuum = 3 x 10^8 m/s
Or = angle of refraction = ?
ni(sinOi) = nR (sinOr)
ni( sinOi)/ nR = sinOr
arcsin(ni(sin0i))/nR = Or
arcsin( 1.0003(sin58.0)) / 1.47
Or = 35.25°
